As the USAF found out in the Balkans, Stealth can be defeated (one F-117 was toasted). Stealth airframes/planforms are relatively static through the life of the aircraft, while radars and electronic detection systems are constantly being updated.
Stealth isn't an invisibility shield, enough power and an enemy can burn through it. While the F-22's RCS is quite tiny, there remains the possibility if not probability that clever enemy electronics manufacturers could devise airborne systems to marginalize this advantage.
The F-22 has much more going for it than just stealth though. With those massive engines independently vectored to 20 degrees (+/-), the power and agility of the Raptor makes it a potent fighter even if it was painted chrome and powered up a radar transponder.
Previous generation planes can engage the F-22, but not well and will always be at a severe disadvantage. However, the edge will shrink as enemies counter with steadily improving radars and IR detection systems.
